Red Sox acquired LHP Mike Myers from the Cardinals for OF Carlos de la Cruz and LHP Kevin Ool.
Myers will probably get the final spot in the Boston pen over Blaine Neal and Byung-Hyun Kim, who figures to be traded. De la Cruz, 20, hit .274/.341/.338 for short-season Single-A Lowell last season. Ool, a potential lefty specialist, is more likely to have a career.
